I built these sort of jungle wood support beams on the walls and I think I really like them actually!

A cobblestone wall supported by jungle logs. The logs are interconnected through jungle wood fences. The middle of each compartment formed by the logs and fences has a lit redstone lamp.

The redstone lamp was a really good idea too, I get really lazy when it comes to placing torches on the surface because you basically have to wait until night to figure out if you put them at an optimal distance. The wall setup certainly isn't optimal because the lamps are pretty close together, but it is pretty and lights up a good area.

The wall extends past a narrow passage besides a house made out of cherry and oak wood and cobblestone.

The side passage on that side of the house is kinda tight now, and the view on the upstairs balcony is worse now, but it's a sacrifice I'm willing to make.

I've also put minecarts on the bridge!

A gravel and stone bridge bordered by oak fences, with two minecraft tracks in the center separated by one block.

I forgot what the original intent behind having two minecart tracks was to be honest. Though I'm thinking of using one of them as a track exclusive to minecarts with chest to move items to and from the new smelter. I'm also tempted to remodel the bridge to have this same support style as the wall, but I don't know if that'd make it too samey.

Speaking of, the new smelter! The outside is still kinda ugly, I'll definitely be detailing it more in the future.

A structure made out of deepslate bricks. The outside of the building has a crimson plank floor. The inside has copper grating and minecarts visible through the entrance and windows.

For the inside I just watched a youtube tutorial. I don't know a ton about redstone but that is something I want to learn in the future. Maybe have a kelp or bamboo farm that auto fuels the smelter.

The interior of the smelter. The ground is made out of copper grating.The smelter itself is made out of hoppers, minecart rails, furnaces and smooth stone.

I was doing crimson planks to mirror the mob farm underneath but I don't really like it. I'm still unsure what I'm gonna do outside other than maybe extend the second minecart track to be able to reach the smelter chest. If I pave the outside at all I'll probably use smooth stone like I used for the underground floor where the chest is.

A corridor made out of smooth stone with lit redstone lamps on the floor. There is a chest that receives items from the smelter above.
